SWIVEL CLENCHER-ABIVI.

Application filed June 30, 1914. -Serial No. 848,498.

To all whom it may concern Be it known that I, ADELBERT S. JA UITH, citizen of the United States, residing at Boston, in the county of Suffolk and State ofliiassachusetts, (whose post-otfice address is 4:2 Irwin street, WVinthrop,Massachusetts,) have invented a new and useful Improvement in Swivel clencher-Arms for Wire Stitching or Stapling Machines, of which the following is a specification.

l/Iy v invention relates generally to wire stitching or stapling machines, in which round or flat wire is fed into the machine and there formed into staples, which are instantly forced into the material of a barrel, box, or container and clenched on the opposite side; and particularly to such machines driven by hand, foot or power, when adapted to and used for the purpose of fastening together the component parts of square, rectangular, round or oval boxes, barrels and containers composed of paper, straw board, pulp board, binders board and the like.

My objects in making said invention are: first, to quickly and securely fasten together two or more pieces of the component parts of square rectangular, round, or oval boxes, barrels or containers by means of wire staples; second, to provide a device so constructed as to be readily adjustable to the different thicknesses, sizes and forms of boxes, barrels and containers usually com posed of paper, straw board, pulp board, binders board and the like; third, to provide a device that shall firmly clench the wire staples as soon as they are driven through the boX material; fourth, to perform its functions rapidly and with as great a degree of automatic action as possible.

I attain these important and valuable objects by means of the mechanism illustrated in the accompanying drawings, in which.-

vertical section of these operative parts at right angles to the section shown in Fig. .7; Fig. 9 is a vertical section similar to that shown in Fig. 8, but showing the parts in position for the second operation of staple forming; Fig. 10 is a vertical section of the same parts at right angles to the section shown in Fig. 9; Fig. 11 is a vertical section similar to that shown in Fig. 10, but showing theoperative parts in position for the final operation of clenching the driven staple, and Fig. 12 is a vertical section of these parts at right angles to the section shown in Fig. 11.

Similar reference letters refer to similar zontal head piece a, in which is journaled a horizontal shaft having upon its rear end the driving pulley B, which is detachably attached. to said shaft by means of a clutch operated by the foot lever Z). Upon the front end of said shaft is fixed the icams operating the staple forming and driving mechanism and the staple wire feeding mechanism, commonly known as the stitcher head, and hereinafter more particularly referred to. and all of which. is of the usual and well known construction and operation. Fixed to the vertical column A, 'is the bracket C. upon which is formed the verti' cal dovetail projection c, to which is fitted theright angle supporting arm D, the outer end of which is bored vertically to receive a similarly formed part 6, upon the lower end of the clencher arm E. This arm is tapered from its base upward and rises at an inclination, its upper end being directly under the staple forming mechanism in the stitching head of the machine proper. This is its operative position. The clencher arm E, swivels or swings to the front and left whenever it is necessary to moveits upper end from its operative position. TV ien inits operative position it is locked by the locking pin F, (Fig. 6,) which slides in its holder 7", fixed to the top of the right angle arm D. The locking pin F, is fitted to enter the slot in the locking block d, fixed to the flange at the base of the clencher arm E, as shown in Fig. 6. This locking pin is withdrawn from contact with the locking block d, by means of the foot lever G, acting through the rock shaft G, lever g, connecting rod 9, and the right angle lever 9, (Fig. 3,) and is forced into the locking block slot by means of the helical spring f. The right angle arm D, clencher arm E, and its connections are vertically adjustable by means of the screw cl and hand wheel cl, and clamped in any position desired by the clamping lever a, so that various thicknesses from 0 to inch can be stapled.

Referring to Fig. 6 it will be seen that the right angled arm D, is divided. by a narrow vertical slot, thereby providing for a slight variation in the width of the vertical dovetail slot inclosing the dovetail 0, which is formed upon the bracket C, fixed to the vertical column A. Passing in a horizontal direction through the right angled arm I), is a clamping screw, upon the end of which is fixed the clamping lever 6, by which it may be tightened or loosened at will. These parts are constructed in the ordinary and well known manner usual in such cases.

The foot lever G is adjustable upon the rock shaft G, by means of its divided end and clamping screw 2. When the locking pin F, is withdrawn from the locking slot in the locking block d, the clencher arm E, is swung to the front and around to the left by means of the helical spring h, acting upon the connecting rod it, which is pivoted to the cap plate lever H, fixed to the lower end of the cylindrical part 6, of the clencher arm E.

In the operation of driving and clenching the ordinary staple through flat work there are five distinct operations, namely: first, to feed in the wire; second, to cut off the piece of wire of the proper length to form the staple; third, to form the staple with its ends projecting downward, ready for driving; fourth, driving the staple; and fifth, clenching the points of the staple tightly and firmly. In driving a staple through two pieces of material at right angles, as the corner of a box, an additional function is required, that of turning the ends inwardly, toward each other so as to pass through the material at nearly a right angle on each. side of a vertical center line of the work, the material being at an angle of 45 degrees. The first four of the operations above recited are performed by the mechanism above the clencher arm, and the fifth, or final operation by the mechanism of the clencher arm itself. This mechanism is provided with guides and gages for supporting and retaining the material to be stapled in its proper position. These requirements are met by the clencher arm it, its appendages and operative parts as follows:

Referring to Fig. 2, a vertical. rod 1, (shown in dotted lines,) is connected with the vertical cam rod of the stitching head K, in the usual manner. Its lower end is pivoted to the bell crank 6, (shown in dotted lines,) whose upright portion is connected by the rod 7', with the lever L, which is fixed to the rock shaft M, to which is fixed the lever N, which in turn is connected with the bell crank O, by the swivel rod is. The bell crank O, is connected by the rod Z, with the bell crank P. This is connected with the clencher Y, by the rod m. By this mechanism the operative parts in the stitching head K, and those of the clencher arm E, work in unison in forming and driving and also in clenching the staple.

For the purpose of supporting the box, barrel or container and its component parts to he stapled, the supporting guide loop R, is provided. This is detachably attached to the block 1* (Figs. 4% and 5,) by the thumb screw S. The block 7", runs in a dovetail slot formed in the upper surface of the clencher arm E, making it adjustable at any point along the length of said arm, and therefore providing a support for all sizes of boxes, barrels, containers and covers within the range of the device, as shown in Fig. 1. Upon the block 1", is also the gage it, having a projecting lip as shown, and secured by the thumb nut which serves to gage all thicknesses and forms of boxes and covers, and particularly to support the rims of box covers.

The outer side of the inclined arm E, and the outer side of the inclined head T, constitute respectively a box-body-supporting face, and a box-end supporting face, said faces being oppositely inclined relatively to the path in which the staples are driven, and meeting to form a right angled box-cornersupporting apex. The wire stitchin g head is organized and arranged to so drive each staple that one leg passes at one side of the apex through the body member, and the other leg at the opposite side of the apex through the end member of a box 1 supported by said faces. The oppositely inclined end faces on the reciprocating clencher are arranged to clench the two staple legs simultaneously against the inner surfaces of the box body and he and The neck of the staple is bent by the driving mechanism across the box corner supported by the apex, said apex and corner forming an anvil across which the staple neck is bent. The upper side of the inclined arm E, and the apex formed by the junction of said arm and the head plate T, are curved as indicated by Figs. 8, 10 and 12, and by dotted lines in Fig. 1, the form of said upper side and apex being such that the assembled body and head of a substantially circular container are adapted to rotate on the arm and head plate, so that the continuous circular corner formed by the intersection of the container body and head is movable in an endless circular path in which the said apex is located. The staples are, therefore, driven in an endless circular series, as indicated in Fig. 1, without removing the work from the arm and each staple is spaced from the one previously driven, by imparting a sufiicient partial rotation of the body and head of the container to cause the last staple to leave the apex and bring another portion of said corner onto the apex in position to receive the next staple.

The upper end of the clencher arm E, is formed at rightangles to its upper side and to it is fixed the head plate T, which serves as a broader support for the work.

The operation of my device is as follows: The swivel clencher arm is placed at an angle of 415 degrees, so that when a barrel, ring, or cylindrical part of a round or oval box, barrel or container is placed upon it, and the top or bottom of said box, barrel or container is placed on the head plate of the clencher arm, the edges of both the barrel or ring, and of the top or bottom meet so that a degree staple will securely fasten both together when properly driven. The object of placing the clencher arm at an angle of 15 degrees is to allow a symmetrical staple of 90 degrees to be properly driven into the box at the point where the edges meet, as already described.

Operation No. 1: The swivel clencher arm being in position to receive the barrel, ring, or cylindrical part of the box; the operator places the barrel, ring, or cylindrical part on the arm and in turn pushes the swivel clencher arm into its operating position where it is automatically locked. Then by placing the top or bottom, (as the case may be,) of the box, barrel or container on the head plate of the arm, so that the edge of the barrel, ring or cylindrical part, and the top or bottom of the box, barrel or container meet, the box is ready to receive the staple.

Operation No. 2: In stapling boxes, the operator places one hand on the barrel, ring or cylindrical part of the box as it rests on the swivel clencher arm, and the other hand on the top or bottom of the box, barrel or container as it rests on the head plate of the swivel clencher arm, and in this manner turns the component parts'of the box into position for receiving the successive staples.

Operation No. 3: When the box, barrel or container is completely stapled, the operator 1 by pressing the foot lever unlocks the arm, which automatically swings toward the operator and stops in a position which allows the operator ample room between the swivel clencher arm and the stitcher head to remove the completed box. This operation is repeated, the foot lever G, depressed, the

locking pin F, released, the helical spring h, acting through the plate lever H, swinging the clencher arm forward and to the left,
